Could anyone explain to me the basic incomes and expenditures of going to uni in Scotland. If I went to Uni for 5 years to do a masters degree in engineering, Do the tutition fees get paid for all 5 years?

Incomes: Savings, Bursary, Student Loan, Part time job. Is there any more?

If you live anywhere in the EU except England you will not pay tuition fees. If you live in England you will pay half the English tuition fee. They will certainly fund the first 4 years (the undergrad portion), not sure about the 5th though.
